How did Prusa hold the industry back? Were they suing other printer manufacturers who innovated?

"Not innovating myself" isn't the same as "holding other's innovations back".

I didn’t say Prusa held the industry back; I said they sat on their haunches. Even the basic differences in stepper motors between what bambu chose and what prusa or ultimaker chose demonstrates my point.

Edit: whoops! guess i did say they held the industry back... my bad /facepalm.
